Network Sharing: Support of Multi-Operator Core Network by GERAN (MOCN-GERAN)

By agaur on December 22, 2012
Network Sharing - MOCN GERAN
With a number of spectrum reframing (e.g. 900 MHz spectrum re-farming) being done to free up band for LTE technology use, operators may have to reduce their GSM capacity and may share their GSM networks. As re-farming significantly reduces the set of frequencies allocated to GSM, 3GPP decided to look in to the RAN sharing method and along with supporting companies found that MOCN (Multiple-Operator Core Network) is optimal RAN Sharing method.

Local Call Local Switch System (LCLS) Overview

By agaur on December 7, 2012
Local Call Local Switch System Architecture
The transmission path is an important part of wireless networks. In wide rural areas or in remote areas, operators sometimes face the challenges to deploy networks due to the lack of or cost of fast and reliable backhaul transport network. Statistical data indicate that many calls in a mobile network in these areas are local calls. There is good probability that call between two terminals go via same BTS or in between co-located BTSs or with in same BSC.

Introduction to Cognitive Radio (CR)

By pankaj on November 29, 2012
Cognitive Radio
Communication devices today are becoming ever more sophisticated and diverse, delivering a plethora of new services and applications. The last hop to the end user, a person or device, is increasingly being delivered wirelessly. This sophistication brings with it complexity, making conventional approaches to organisation, implementation and regulation increasingly inadequate.

Seamless WLAN Offload with IP Mobility

By agaur on November 6, 2012
Evolved Packet System
Wireless service provides across the globe are aiming to lower the cost for providing data service while meeting the increased demand due to exponential growth in mobile data traffic thanks to popular smartphones.  Since few years, Wi-Fi  offload had been a preferred choice for operators to balance the IP traffic. However, WiFi offload is not often seamless to end user.

Cellular Heterogeneous Networks: Networks of Multiple Radio Access Technologies

By agaur on October 21, 2012
Heterogeneous Networks
Cellular standards have evolved rapidly in last couple of decades and as of today multiple mobile access technologies exist in operator’s network.  Increased demand for low cost mobile broadband connectivity is driving the development of heterogeneous cellular networks.

Wireless Body Area Network (WBAN) - A Health Monitoring Technology

By kamal on October 16, 2012
Wireless Body Area Network
Wireless sensor technologies have seen as rapid growth in recent years. This rapid technological advances resulted in low cost, light weight, small size and intelligent wireless sensor nodes. These nodes can be strategically placed on the human boday and connected by means of wireless network. This arrangement of wirelessly connected sensor nodes on the human body is known as Wireless Body Area Network (IEEE 802.15.6).

Minimization of Drive Test (MDT) in LTE-Advanced

By kamal on October 10, 2012
MDT
Drive tests are very important in Mobile cellular communication. Drive tests are done by the operators to discover problems in the network such as "coverage holes". Drive tests help the operator to maintain and improve the quality of the network, for example, by identifying the need for tuning of network parameters to achieve better coverage.

LTE Packet Data Convergence Protocol (PDCP) Overview

By agaur on October 6, 2012
PDCP
Similar to UMTS technology, Packet Data Convergence Protocol (PDCP) is located above the RLC layer at UE as well as in eNB. However in LTE, all user data goes via the PDCP layer as ciphering is performed in PDCP.  The main functions of PDCP are IP header compression (UP), ciphering and integrity protection (Control Plane only). PDCP layer also carries RRC signaling messages as well so it is part of control plane as well.

LTE Radio Interface – Layers, Channels & Physical Layer Functions

By kamal on September 29, 2012
LTE Radio Interface Layers
LTE radio interface consists of 3 layers,
Layer 1 – Physical Layer
Physical layer offers data transport services to MAC layer.
Main functions of physical layer include: Mapping of transport channels on to the physical channels, forward error correction (FEC), Modulation & Coding etc.
Layer 2 Sublayer – Medium Access Control (MAC)
